Sadly I have no more idea, If you're comfortable with arduino you should make a custom sketch in order to test your hardware : https://arduinodiy.wordpress.com/2012/05/06/7-segment-display-on-arduino-with-595/
EDIT ; Have you followed the shematics provided in the package "74HC595 EXTERNAL GEAR INDICATOR SCHEMATICS.doc" or something else ?
